Abstract: A feedback generation method for uplink Transmit Power Control (TPC) in a mobile communication system is provided. A feedback generation system for uplink TPC includes an uplink information receiver to receive uplink information from a terminal, to measure a Signal-to-Interference Noise Ratio (SINR) value with respect to the received uplink information, and to measure a movement speed of the terminal, a transmission power adjustment value setting unit to set a transmission power adjustment value based on the movement speed of the terminal; an adjusted SINR calculator to calculate an adjusted SINR value, based on an expected SINR value and the measured SINR value; and a feedback information regenerator to regenerate feedback information based on the transmission power adjustment value and the adjusted SINR value, and to transmit the regenerated feedback information to the terminal.

Abstract: Disclosed is a method of deciding a radio link failure at a base station. The method includes initializing a signal quality degradation count value, measuring an uplink signal quality at predetermined time intervals, and increasing the signal quality degradation count value when the uplink signal quality is less than a predetermined lower limit quality threshold value, wherein a radio link failure is decided when the signal quality degradation count value reaches a predetermined radio link failure decision threshold value while the measuring of the uplink signal quality and the increasing of the signal quality degradation count value are repetitively performed a predetermined number of times.

Abstract: Provided is a method for estimating a frequency offset. The method for estimating the frequency offset may include calculating autocorrelation values associated with a Cyclic Prefix (CP) for a reception signal, dividing the calculated autocorrelation values into first autocorrelation values associated with an interval where a signal exists and second autocorrelation values associated with an interval where a signal does not exist, determining whether to use the divided second autocorrelation values; and estimating the frequency offset using the second autocorrelation values determined to be used and the first autocorrelation values.
